SITRANS LR100 series are 80 GHz compact radar transmitters with Bluetooth wireless technology. Featuring a narrow beam for flexible installations in existing vessel openings – or non-intrusively through plastic vessels.
The series consists of three transmitters:
SITRANS LR100 for basic measurement to 8m
SITRANS LR110 with communication and hazardous approvals options and range to 15m
SITRANS LR120 with communication, longest range to 30m and optional submergence shield for flooding protection.
Benefits
Easy Bluetooth® wireless technology for easy and quick setup with Siemens SITRANS mobile IQ App
80 GHz narrow beam and small size allows for the easiest installation and commissioning
Custom radar microchip means signal killer conditions like condensation, buildup or fluffy solids are no match for the extreme sensitivity of the microchip, the weakest signals are still detected
Zero blanking zone allows measurement range right up to the sensor and with an accuracy of 2 mm you can get rid of costly manual measurement methods
Digitalization and Industry 4.0 ready with HART 7.0 or optional Modbus RTU for intelligent, value adding data locally or to the cloud
